Abstract

The invention relates to a device ensuring improved electrical contact between an electrical conductor (12) and an electrode (14). This device is characterised in that it comprises an element (50) forming a fixed position contact nut, an electrically conductive material, containing an axial through orifice (52) into which passes the electrode (14) or an electrode-holder element (16), this electrical conductor (12) finishing up at the nut-forming element (50) with a connection stem (54). This nut-forming element (50) can be constructed as two half-discs (50a,50b). In this way there is obtained an assembling and disassembling facility, as well as improved electrical contact during operation. <IMAGE>
